If you don't know who Legion is, here is a quick rundown from his comic book roots.

David Haller is the powerful Omega-level mutant known as Legion. He possesses hundreds of mutant abilities ranging from telekinesis to reality warping, but each power is controlled by a different persona, which could be either benevolent or malevolent.

Legion is a lesser known character in the X-Men comic book universe, but come February everyone will know who he is as the new series looks both brilliant and mind-bending at the same time.

Come February, we will be on top of everything Legion, with live recaps and plenty more. For all things Legion, keep it right here on ComicBook.com!

Legion is created by Noah Hawley (Fargo), who will also serve as showrunner, and is a co-production of Marvel Television and FX Productions. Legion stars Dan Stevens as David Haller, along with Rachel Keller, Jean Smart, Aubrey Plaza, Jeremie Harris, Amber Midthunder, Katie Aselton, and Bill Irwin.
